Thats what i'm referring too, the damage trick. When an explosive is triggered, but i'm currently trying to find a way to make a structure of reasonable size collapse. Making gameplay slightly more enjoyable knowing an explosive or some other game objective has an added effect to gameplay.
i like imagining a tower/spire or some other structure exploding violently, tossing debris everywhere and completely changing the map layout, not to mention the possibility of collateral damage. etc (Which if possible could lead to the creation of a unique invasion map/gametype i've wanted to create for sometime)
But yes, i shall try posting this in the Reach forum, going on your logic.
